BoxLings is an interactive CLI tool inspired by rustlings that teaches BoxLang through 129 progressive exercises across 28 topics. It integrates TDD/BDD as a first-class learning skill using the TestBox framework, guiding learners from reading failing tests to writing their own specs and completing full red-green-refactor cycles. The tool runs in watch mode, automatically re-executing exercises on file save, and covers topics from basic variables and functions through async programming, Java interop, destructuring, and CLI app development. It requires BoxLang 1.12+ and is fully self-contained for offline use.
